To (1Z1 107mm it may concern:

Be it known that I. Eowaun A. Bruno, a States, having a legal State of Maryland, and rein said State, have invented certain new and useful i Improvements in 'lype-'riting Machines, of which the following is a specification.

This invention relates to typewriters, having special reference to a machine with a novel frame and the details thereof.

An object of the invention is to provid a machine of this character with an improved paper feed. the construction of the machine admitting the introduction of the paper into the front thereof.

Another object of the invention is to provide and position the operative parts of a typewriting machine in proximity to each other to make possible the use of mechanical elements of the simplest order to insure the speed of the operation of the machine.

A further object of the invention is to provide a paper carriage of such a structure as to admit the paper being carried in sub- .stantially the same line of direction througlr out its course through the machine so that the writing upon the same will at all times he in full view of the operator and notations may he made thereon without the operation of any part of the machine.

A still further object of the invention' is to provide an improved mechanism whereby the line spacing is effected automatically with each reci 'n'ocation of the paper carriage to the right position of the machine whereby the distance between the lines of writing on the paper can be regulated by the operator.

In the following description and claims and in the accompanying drawings, which show a preferred embodiment of my invention other objects and advantages will be disclosed and pointed out: and it will he understood that changes in the structure and operation of this machine may be made within the scope of the claims without departing from the description hereinafter brought out.

In the drawing: Figure l is a top plan view of a portion of the improved typewriter showing the novel features thereof. Fig. 2 is a transverse central section of the same. Fig. 3 is a side elevation of the line spacing mechanism in a disengaged position. Fig. 4 is a top plan view of the same residence in the partly in section and in an engaged tion. l ig. 5 is a top plan view of form oi line spacing mechanism in gaged position. Fig. (i. is a d clutch members shown in Fig. 5 gaged position.

Referring now specifically to the drawings: The machine comprises a base 13 which is preferably of rectangular forinalion and composed of sheet steel and which is provided ipon its upper face lllttl-lllQtlh atcly thereof and near the rear edge with longitudinally disposed tracks 1e and i7. are provided upon posi another an entail of the in a disenlhe tracks: 16 and 17 their upper faces with longitudinal grooves 18 and l in which are disposed suitable roller bearings 20 and 21 which engage in grooves and formed in the uppcredges of the legs 2% and 25 on which is supported the paper carriage. The paper carriage comprises harsdo which are laterally disposed across theoppositc ends of the carriage and are supported upon the upper extrcmities of the legs 2-1: and 2.3. The forward extremities of the bars 26 are provided with vertically disposed slots 37 which are adapted to receive the opposite ends of a shaft 28 upon which is mounted the platen 29 over which the paper is passed. in the forward ends of the bars 26 is disposed longitiulinaltv a rod 30 supporting intermcdiately thereon a pair oi short clips 31 and at its CXtl'Cll'lltlQS a second pair of tflill'S 32 which are of greater length than the clips 31. The bars 26 support across their extreme forward ends a rack bar 33 the engaging teeth of which extend upwardly and forwardly for the purpose of engaging the cscapement mechanism.

For the purpose of su iporting the paper in a horizontal position in full view of the operator after it passes over the platen 29 a metallic plate 34 is positioned longitudinally across the bars .26 and secured thereon in any suitable manner. The forward edge of the plate Zl-l is slightly beveled to conform lo the cylindrical contour of the platen 29 for the purpose of clcsel v fitting against the same for the more posiiive guidance cf the paper thereover. To the plate 3i: near its forward opposite edges hy means of the thumb screws 35 are secured the dctcnt springs- .it'i carrying the rollers 37 adaplcd to operate in the notched wheels 38. all in the ('llsi'(1lll1ll' manner to hrld the platen in a straight line against accidental displaceill.)

i the diagonally disposed feed plate 58 which extends backwardly and upwardly from the ment during the operation of the letter spacmechanism The plate 8% carries the raised flanges 34 at the opposite intermediate forward edges thereof for the purpose of straightening the paper should it be passing through the machine croohedly and for the purpose of keeping the paper from passing through the machine in any wa other than the straight a. way.

Upon the paper carriage at the front thereof by means of the thumb screw 39 the flange 10 of the bar 11 is secured. The bar 11 is provided at its forward extremity with a graduated rod -13 which slides in the end of the bar '11 and is secured in its different po sitions by the thumb screw l2. The bar 13 carries the fiange 11 which flange comprises the paper edge gage.

Il'lounted upon the extremity of the shaft 28 is a beveled roller -15 the reduced portion of which extends outwardly and is adapted to be engaged by a concave clutch 46 provided upon its inner surface with a strip of leather a? or like material for the purpose of producing frictional engagement between the roller and the clutch 46. The clutch 16 is carried upon the extremity of a plunger which is slidably mounted in the upper end of a standard 49 and is prevented from being displaced therefrom by a flange which is annularly formed upon the opposite extremity of the plunger For the purpose of normally holding the plunger as in an extended position a coil spring 51 is mounted about the plunger the opposite ends of which are impinged against the clutch member t6 and the face of the standard 4:9. For the purpose of imparting a partial rotation to the plunger 48 a set screw is adjustably mounted in the laterally disposed slot formed in the upper face of the standard 19 the set screw 52 extending downwardly to the plunger 18 engaging the same in one of a plurality of diagonally disposed groovcs 5-1, or in the face of the plunger 18 according to the position of the set-screw in the slot 58. The standard 19 is supported on the base plate 15 in direct alinement with the track 16 to effect the proper registration of the roller and the clutch 16.

The base 15 carri depending flange 5:

upon its front edge a which forms a part of 57 to a pointin l 'll'fifilll'lltjf to the 29. The plate extends the entire length of the base 15 and is secured to the same. Plate 58 is provided upon its upper edge with a beveled portion for the purpose of closely fitting against the outer surface of the platen 29 to provide a positive guiding means for the conveyance of the paper on to the platen 29 beneath the clips 31 and 32.

flange platen The base plate 15 supports intermediately of its opposite ends the vertically disposed standards 59 'which support at their upper extremities bar 60. The bar is used for the purpose of supporting the upper operative mechanism of the machine.

Upon the rear of the paper carriage is mounted in a suitable manner the bar 63 which reciprocates adjacent the bar 6% which is solidly mounted in a suitable manner with the base of the machine. Bars 63 and 64 are for the purpose of carrying mechanism not shown or claimed in this application.

In Fig. 6 the members 61 and 62 represent a tooth clutch mechanism for the line spacing already set out. I

The operation of the machine is as follows: The operator inserts a sheet of paper bachwardly into the machine upon the diagonally disposed feed plate 58 and against the edge gage member 44 if desired and places the same against the platen 29 which by its curvature directs the forward edge of the paper against the clips 31 and 32 to impinge the paper upon the upper face of the platen 29. \Vhen the paper is in this position and the machine is actuated by the escapement (not shown) the carriage is reciprocated the length of the base 15 upon the roller bearings 18 and 19 which engage in the upper faces ofthe tracks 16 and 17. This standard 49 being positioned upon the right end of the base 15 and carrying the line spacing mechanism thereon, the platen 29 is caused to partially rotate and to feed the paper forwardly a distance controlled by the positioning of the setscrew in one of the grooves 54, 55 or 56. As is shown in the drawings the grooves 54, 55 and 56 are disposed upon the plunger 18 at different angles to effect different degrees of rotation corresponding to the distance desired, one space two spaces or three spaces, between the lines of writing upon the paper disposed upon the platen 29.

The operation of the line spacing mechanism is as follows: lVhen the paper carriage is actuated to travel to the right of the machine the conical roller 45 which is keyed to the shaft 28 which rigidly supports the platen 29 engages in the clutch member 46 and is impinged against the friction packing 17 and as the paper carriage is further actuated to the extreme right position of toward the standard 19 contracting the spring 51 and causing the plunger 4:8 to slide backwardly engaging the set-screw 5'2 in one of the grooves 54:, 55 or 56 and thus causing a partial forward rotation of the clutch 4:6 revolves the roller 45 and carries the platen 29 through the same angle of rotation. This line spacing is effected at each reciprocation of the paper carriage to the right position of the machine and feeds the machine the clutch member 46 is forced the paper backwardly of the machine on to the horizontally disposed plate 34. Owing to the horizontal position of the plate 3f the paper is kept in a horizontal position throughout the operation of the machine so that the operator is enabled to read or to check the writing disposed upon the papa after it has passed over the revoluble platen 29.
